ND Studio

Educator's Arcade

Classroom games that catch the exact wrong move.

More than 100 no-prep digital learning games and 3D labs for math, science and ELA, grades 3 to 12. When a student adds the denominators or reads the arrow backwards, the game says so, by name.

One file. Works offline.

Each game is a single HTML file that runs on a Chromebook with no wifi.

No accounts. No student data.

Students open it and play. Nothing is collected, so there is nothing to approve.

Three levels in every game.

Rookie, Varsity and Nationals, so one file covers the whole room.

A report at the end.

Each student gets a skill report, and you get five discussion questions.

Questions teachers ask

How the games work.

Do the games work on Chromebooks?

Yes. Each game is a single HTML file that opens in the browser. It runs on a Chromebook, a laptop or a desktop, and it keeps working with no wifi once the file is open.

Do students need an account or a login?

No. Students open the game and play. There are no accounts, and the games do not collect, store or send any student data, so there is nothing for your district to approve.

How do I assign a game to my class?

Every download comes with a teacher guide that walks through four ways to hand it out: Google Classroom, Canvas, Schoology or a Google Site. You can also put the file on a shared drive.

How do the games handle different levels?

Every game has three levels, Rookie, Varsity and Nationals, so one file covers the whole room. Each game runs in six short acts that build from the idea to the hard cases.

What do I get as the teacher?

At the end each student gets a skill report showing what they have and what they missed. The teacher guide adds five discussion questions with model answers, a scoring rubric and the standards the game covers.

What does "catches the exact wrong move" mean?

Each wrong answer in a game is a real misconception, such as adding the denominators or reading the arrow backwards. When a student picks it, the game names that mistake and shows why it fails, instead of just marking it wrong.

Where do I buy the games?

The full catalog is in the Educator's Arcade store on Teachers Pay Teachers. Games are sold one at a time or as a bundle for each track, and every track has a free game to try first.
